PURPOSE: A method for the estimation of cooling speed according to thickness of a high tensile heavy thickness steel plate is provided to arrange a manufacturing foundation to minimize a difference between the cooling speed inside and the cooling speed outside of the surface of a heavy thickness steel plate, and to minimize the material deviation of the inside of the heavy thickness steel plate.;CONSTITUTION: A method for the estimation of thickness-specific cooling speed of a high tensile heavy thickness steel plate comprises the following steps: simulating(S10) a steel plate manufacturing process including the cooling speed conditions of test pieces different from each other; obtaining(S20) a microstructure and test piece hardness value from each test piece; and estimating(S30) the thickness-specific cooling speed of a steel plate by comparing each thickness-specific structure and hardness value with thickness of other parts of a steel plate produced by the manufacturing process. The thickness-specific structure value and the hardness value of a heavy thickness steel plate are stored after a heavy thickness steel plate manufacturing process including heating, rolling and cooling is processed, and the thickness-specific structure value and hardness value of the processed steel plate are obtained before the first step.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S10) Step of simulating a steel plate manufacturing process; (S20) Obtaining the microstructure and hardness value of a test piece; (S30) Measuring the thickness-specific cooling speed of a steel plate
